What Is WBC Test ?
A WBC (White Blood Cell) blood Test is a medical test that measures the number of white blood cells in your blood. White blood cells are an essential part of the immune system and help protect the body from infections, bacteria, viruses, and other harmful invaders.
Doctors use this test to:
Detect infections or inflammation
Diagnose immune system disorders
Monitor blood-related diseases (e.g., leukemia)
Assess how well treatments (like chemotherapy) are working
A normal WBC count typically ranges between 4,000 to 11,000 cells per microliter of blood, but this may vary based on age, health conditions, and laboratory standards.
High WBC Count (Leukocytosis): May indicate infection, inflammation, stress, or blood disorders.
Low WBC Count (Leukopenia): May be caused by viral infections, autoimmune diseases, or bone marrow problems.
